Your question is very vague. What exactly do you mean by "the same results"? And which "alternative tools"? How do those tools provide "an alternative"?
I don't think you're getting downvoted because you're not praising a piece of technology; you're getting downvoted because your tone seems rude, arrogant, and like you're on a witch-hunt rather than an honest inquiry. While tech fan-clubs do exist on HN, in my experience they respond quite constructively to reasoned criticism--if it's not phrased in an unkind way.
I'm not for or against Erlang. While honestly attempting to learn something new today, I became frustrated with how devoid of content most of the comments in this thread are. "I'm {senior title}, and {tech name} is great" is as far as most of the comments go. That's just extremely mediocre.
A comment section isn't the place to look for detailed content so why get frustrated about the brevity here? There are plenty of places to deep dive in the internet.
